Toxicological interactions between carcinogenic and weakly carcinogenic mixtures in the mouse skin initiation-promotion system

Conference ·
OSTI ID:6331132
We previously observed that the carcinogenic activity of the neutral fraction of a coal gasifier tar was greater in the absence of the other tar components. Other investigators showed that the dermal tumor-initiating activity of benzo(a)pyrene (BaP) and the binding of BaP to mouse skin DNA was diminished when the BaP was administered in the presence of coal liquids. In the present study we found that the weakly tumorigenic polar neutral fraction of the gasifier tar diminished the tumor-initiating activity of the PAH-enriched fraction at one dose level, but not at another. 20 refs., 1 fig., 2 tabs.
